It seems something is leaking on the back of the block and has spread from just below where the oil filter is to the top of the oil pan, I wasnt able to tell exactly where it was coming from with a quick inspection. Im thinking it may be a bad oil cooler o-ring. Are there any other common leaks that occur on 5th gens in the general area?

 

Do you have an aftermarket oil pressure gauge? If so, check the sending unit. If not that it is most likely the oil cooler o-ring.

 

No its stock.

Ok thanks guys
